A strand of primary conductive plant tissue consisting chiefly of xylem and phloem. Also called fibrovascular bundle.

vascular bundle

a structure of vascular plants that runs up through the roots, into the stems and out into the leaves, and whose function is transport within the plant. Water and ions are transported mainly by XYLEM, and dissolved organic solutes mainly by the PHLOEM. Some vascular bundles are described as open since they contain dividing CAMBIUM tissue between the xylem and phloem.

One relatively consistent feature of most other Poales is the presence of phytoliths in the leaf epidermis, rather than in the vascular bundle sheath cells, as in most other commelinids (Prychid et al., 2003).
These two 4-carbon compounds are then transferred in to the bundle sheath cells, where they are decarboxylated (carbon is dropped off).
